PLOW.

SPECIFICATION forming part of Letters Patent No. 478,273, dated July 5, 1892.

Application filed February 26, 1392l Serial No. 422,894. (No model.)

To @ZZ whom it may concern.-

Be it known that we, BENJAMIN FRANKLIN CADENHEAD and MosEs EDWARD BUTT, citizens of the United States, residing at Blountville, in the county of Blount and State of Alabama, have invented a new and useful Plow, of which the following is a specification.

This invention relates to improvements in plows, the objects in View being to provide a plow adapted to be used either as a snbsoiler or as an ordinary cultivating-plow and to enrbody in the construction of the same certain features that may be advantageously used in connection with other plows differing in their construction from the one herein shown and described.

A further object of our invention is to so 'construct the plow as to be especially adapted for breaking lands and for penetrating deep into the underlying subsoil and by its peculiar construction to create a thorough agitation and breaking up of the subsoil without leaving the same at the top ofthe furrow or exposed, but, tothe contrary, leaving said subsoil in the bottom of the furrow and merely turning the soil proper.

Various other objects and advantages of the invention will make themselves obvious by a perusal of the following description, and the novel features thereof will also appear in said description, and will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective of a plow embodying our improvements, the View being taken at the landside thereof. Fig. 2 is a similar view, the view being taken from the mold-board side. Fig. 3 is a rear elevation. Fig. tisafront elevation. Fig. 5 is a detail in perspective of the adjustable landside attachment. Fig. 6 is a detail in perspective of the subsoil point employed for simply loosening wit-hout turing the subsoil. Fig. 7 is a similar view of an ordinary cultivating-point.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing our invention we employ an ordinary plow-beam l and to the same apply the usual handles and clevis, the plow being adapted to be drawn by either one or two horses, as the 'case may he. From the beam depends the usual standard 2, which in this instance, immediately below the beam, is made triangular in cross-section, one face of the standard (the landside) being parallel with the face of the beam at that side, thus leaving the opposite face of the standard at an angle to the beam, as shown, forming a front cutting-edge and also giving the proper angle to the mold-board. Below the reduction just mentioned the standard is forwardly disposed to form a foot 3, which extends some distance under the beam.

To the inclined face heretofore mentioned, with which the standard 2 is provided, there is bolted, as at 4, anv outward and rearwardly disposed turning-wing 5,which constitutes the main turning-wing or mold-board ofthe plow. This wing in transverse vertical section is curved, which curvature is accomplished by the forward bending of the outer lower corner of tho board, as shown at 6.

7 designates a subsoil-plow point, and the same when viewed in transverse section will be seen to be provided at its landside with the perforated foot embracing depending flange 8, through which and the foot 3 a bolt 9 is passed. The point proper has its upper face convexed, and is inclined to conform to the inclination of the foot, while its outer 'edges are beveled to facilitate the penetration of the subsoil. The upper edge or end of the point 7 is considerably below the lower edge or end of themain wing or mold-board 5, so that a space 10 is created between the adjacent edges of the point and win g. This constitutes one portion of our invention-namely, the subsoil-plow-and the operation of the same is as follows: The plowis used as any ordinary plow may be, and the point 7 penetrates, upheaves, and breaks the subsoil located at. the bottom of the furrow and below the soil proper. Asis well known, it is 0bjectionable to turn the subsoil so that it is left at the top of the furrow, and hence, in Order to prevent such turning and create simply a loosening of the same, the space 10 between the subsoil-point 7 and the moldboard is left. Thus it will be seen that although the subsoil-point penetrates well into TOO the subsoil and breaks the same, said subsoil will, instead of being turned, as itwould be were a mold-board present, simply passes over the con vexed face of the point, crumbling and falling back overthe rear edge and from the side of the same and remaining in the bottom of the furrow. ln the meantime themain win g or m old-board 5, servin g at its front edge to cut the upper soil or soil proper, catches the same after the manner of an ordinary plow and turns said soil. From this it will be seen that the subsoil and soil proper, though simultaneously worked or broken, are independently worked or broken, and hence no intermin glin g of the two takes place.

We now come to the second part of our invention; and the same consists of a tlat, plain landside-bar 1l, pivoted upon the bolt 9, that is employed for the purpose of securing the point to the foot; and, furthermore, the attach ment consists in a secondary wing or mold-board 12, which is provided upon its underside with a depending mold-board-supporting flange 13, bolted, as at 14, to the bar 11. lVlien this attachmentis used, a stationary landside 15 is bolted, as at 16, to the foot, and bolted to the rear end of the same, as at 17, is a vertical adjusting-standard 18, having perforations 19 formed at intervals therein. The landside-bar 1l, carrying the mold-board 12, as before stated, is pivoted to the foot, and hence its rear end is vertically adjustable and when so adjusted may be bolted to position by the rear bolt 14 passing through one of the perforations 19 of the vertical adjusting-bar 18. This attachment, it will be observed, may be applied to various styles of plows--such as turn-plows, twisters, shovels, sweeps, bulltongues, scrapes, dsc-and is only employed in this instance when the plow is to be used as anordinary cultivator and not as a subsoiler. Vhen this attachment is employed in the present construction,the point', employed as a subsoil-point, is removed and for it is substituted a point 20, which is longer than the point 7 and extends up to, abuts against, and forms a continuation of the main moldboard 5. lVhen this arrangement ofthe parts has been obtained, the landside-bar 13 is ele vated until the secondary mold-board 12 isat such elevation as to coact with the main moldboard 5, and thus the soil may be thrown lightly toward the growing plants between which the plow passes.

From the foregoing description, in connection with the accompanying drawings, it will be obvious that our invention exemplifies a construction of plow capable of being employed successfully either as a subsoiler or ordinary turn plow and which when employed as the former will simply loosen the subsoil without turning the same to the top of the furrow, but, on the contrary, will leave it at its proper place at the bottom of the furrow, and finally that we provide at attachment for the various styles of plows, whereby the soil may be lightly thrown to a desired extend around a young plant at the landside of the plow.

Having described our invention, what we claim is- 1. ln a subsoil-plow, the combination, with the beam and the standard depending therefrom having its lower end forwardly bent to form afoot and above the same provided with an inclined face or beveled portion forming a front cutting-edge, of the point 7, having a convexed upper sideand provided atitslandside with a depending foot-embracing flange S, a bolt passed through the fiange and foot, and a mainwing or mold-board bolted to the standard at its inclined face and having its outer lower corner forwardly curved, said wing being located solne distance above the point and combining with the latter to form a` passage or space for the subsoil as it leaves the point, substantially as specified.

2. The combination, with the beam, the standard, the mold-board, and point, of a` pivoted landside secured to the point, a secondary mold-board thereon, and means for adjusting said landside, substantially as specified.

3. The combination, with the beam, the standard, the mold-board, and the point, said mold-board being above the point and combining therewith to form an intermediate space or passage, of a supplemental mo1d-board pivotally supported at the landside of the plow above the point and opposite the first-mentioned mold-board, and means for adjusting the same with relation to the main moldboard, substantially as specified.

4. The combination, with the beam, a depending standard, a point, and mold-board, of a rearwardly-extending stationary landside-bar, a'standard rising vertically from the rear end of the bar and provided with perforations, and a lan dside-bar pivoted to the plow and having a rear perforated end, a bolt for adjusting the landside bar being passed through the perforation thereof and any of those ot the standard, and the secondary mold-board bolted to the pivoted landsidebar, substantially as specified.

In testimony that we claim the foregoing as our own we have hereto affixed oursignatures in the presence of two witnesses.
